JACOB BINNIG, OF CAMBRIDGE, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO MASON& HAMLIN, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF DELAWARE.

To all whom it may concern:

Be it known that I, JACOB BINNIG, a citizen of the United States, andresident of Cambridge, county of Middlesex, State of Massachusetts, haveinvented an Improvement in Organs, of which the following description,in connection with the accompanying drawing, is a specification, likeletters on the drawing representing like parts.

This invention relates to organs and especially to the wind-chest andpipe-valves thereof.

It has for its objects to provide a novel construction of wind-chestwhich is practicallynon-leakable; to provide a metallic wind-chest ofnovel construction; to provide a construction in which there are no longpassages of small diameter between the windchest and the pipes and toprovide a novel Way of mounting the pipes upon the windchest.

I will first describe one embodiment of my invention and then point outthe novel features thereof in the appended claims.

In the drawings, Figure 1 is a vertical section through the wind chestof an organ showing one embodiment of my invention; Fig. 2 is a view onthe line 9cx, Fig. 1; Fig. 3 is a perspective view partly in section ofone form of my improved wind-chest; Fig. 4 shows the blank after beingstamped from which the wind-chest is made.

In the present embodiment of my inven tion, the wind-chest is made ofmetal, and it has on one or both sides thereof the pipevalves 4. It mayconveniently be formed from a sheet 17 of metal which has been stampedout, as shown in Fig. 4, to present along each edge two series ofapertures 5 and 6, and which then has been bent into substantiallyU-shape, as shown in Figs. 1 and 3. Extending across from one side ofthe windchest to the other and between the apertures 5 and 6 is apartition 7 which forms the top of the wind-chest proper 3. Each pair ofapertures 5 and 6 constitute the ports of a pipevalve 4.

The pipe-valves may have any suitable or usual construction, and thoseherein shown are similar to what is shown in my Patent No. 825,294,dated July 11, 1906, that is, each pi e valve includes a cap member 21which ts over a flange 22 projecting from the sidej fiof ithe casing 17and inclosing the Specification of Letters Patent.

two ports 5 and 6 of any pair. I have herein shown the pipe valves ofdifferent size, those which operate in conjunction with the larger pipesbeing larger than those which operate in conjunction with the smallerpipes. This arrangement, however, is not essential to the invention.

Each aperture 6 has extending therethrough a tubular member 8, the endof which forms the seat for the diaphragm 9, and the edges of thediaphragm are confined between the cap 21 and the flange 22.

23 designates a conduit leading to the pneumatic.

The space above the partition 7 is divided by transverse partitions 10into a plurality of compartments 11, one for each of the pipes 12. Thesepartitions 10 are so arranged that each port 5 communicates with one ofthe compartments 11, and said compartments thus form part of thepassageways between the wind-chest 3 and the pipes 12.

13 designates the upper board which is secured to the wind-chest in somesuitable way and which forms the top of the compartments 11, said upperboard having ports 30 therein which register with the pipes 12. Asherein shown, said board 13 is held in place by thumb-screws 14 whichare screwed into anchor-blocks 15.

In order to make the construction as compact as possible, the valves 4on the two sides of the wind-chest have a staggered arrangement, asshown in Fig. 2, and the adjacent partitions 10 are oppositely inclined,thus permitting the valves on each side of the wind-chest to be arrangedcomparatively closely together, as best seen in Fig. 2.

This construction is very simple and is inexpensive to manufacture. Thesheet metal casing 17 can be readily stamped or died out and bent intoshape, and when the partitions 7 and 10, which are preferably of metal,are soldered or otherwise secured in place, an absolutely air tightwind-chest is produced with a minimum expenditure of labor and expense.

It will be noted that all the parts of the structure are of metal exceptthe upper board 13 on which the pipes rest, and therefore there will beno danger of any leakage of air occurring through the cracking or slitting of wooden parts, as is the case w ere the wind-chest is made ofwood.

It is an advantage to have the passage leading from the valves to thepipes enlarged as they are by the chambers 11 because when the pipe issounded, the air which passes into the pipe is taken from an enlargedair chamber rather than from a small and more or less constricted duct.

While the casing of the wind-chest is shown as made in one piece bentinto U- shape, yet this is not essential to the invention, one of theimportant features of which is making the wind-chest entirely of metal,and another important feature of which is constructing the wind-chest 3and the compartments 11 within the same casing 17 by means of thepartitions 7 and 10.

While I have illustrated herein one embodiment of my invention, I do notwish to be limited to the construction shown.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In an organ, an elongated wind-chesthaving a plurality of separate compartments above the same, saidcompartments extending transversely of the wind-chest and each beingwider at one end than at the other, a pipe communicating with eachcompartment, and means to control communication between the wind-chestand each compartment.

2. In an organ, an elongated wind-chest having a plurality of separatecompartments above the same, said compartments extending transversely ofthe wind-chest and each being wider at one end than at the other, thewide ends of adjacent compartments being situated on opposite sides ofthe wind-chest, a pipe communicating with each compartment, and means tocontrol communication between the wind-chest and each compartment.

3. In an organ, an elongated wind-chest having metal walls, a pluralityof separate compartments above said wind-chest, saidcompartmentsextending transversely of the wind-chest and each beingwider at one end than at the other, the wide ends of adjacentcompartments being situated on opposite sides of the wind-chest, a pipecommunicating with each compartment, and means to control communicationbetween the windchest and each compartment.

4. In an organ, a plurality of pipes a longitudinally-extendingwind-chest, a series of compartments above the wind-chest and extendingtransversely from one side thereof to the other, each compartmentcommunicating with a pipe, and means exterior to the windchest tocontrol communication between said wind-chest and each compartment.

5. In an organ, a metallic member substantially U-shape in cross sectiondivided by a horizontal partition to present a longitudinallyextendingwind-chest and by other partitions to present transversely-extending VI: I compartments above the wind-chest, and. means to controlcommunlcation between the wind-chest and each compartment.

6. In an organ, a sheet metal member bent into substantially U-shape andhaving two series of the same number of apertures formed therein neareach edge, a partition extending across between the sides of said memberand situated between the two series of apertures on each side, meansforming with said U-shaped member and said partition a number ofseparate compartments above the partition equal to the number ofapertures in each series, and means controlling communication betweeneach aperture of one series and the corresponding aperture of theadjacent series on the same side of the U-shaped member.

7. In an organ, a sheet metal member bent into substantially U-shape andhaving two series of apertures of the same number formed therein neareach edge, a horizontal partition extending across between the sides ofsaid member between the two series of apertures and forming with saidmember a wind-ehest, and means forming above said horizontal partitionseparate compartments which extend from one side of said U-shaped memberto the other, one compartment for each aperture of each of the seriesabove said partition, and valves controlling communication between eachof the latter apertures and the corresponding aperture below thepartition.

8. A wind-chest made from sheet metal which has been punched out topresent two series of holes of the same number along each edge and whichis bent into substantially U- shape, a horizontal partition whichextends from one side to the other of the U-shaped member and which islocated between the two series of holes, other partitions dividing thespace above said horizontal partition into compartments, and a valvecontrolling com munication between each hole of one series and thecorresponding hole of the adjacent series.

9. In a wind instrument, a U-shaped inemher having a horizontalpartition forming with said member a wind-chest and a plurality oftransverse vertical partitions above the horizontal partitions to form aplurality of compartments, and means to control communication betweensaid wind-chest and each of said compartments.

1 0. In a wind instrument, a U-shaped memher, a horizontal partitionextending from one side to the other of said member, said partition andsaid member constituting a windchest, a plurality of transverse verticalpar titions above said horizontal partition, said vertical partitionsforming a lurality of separate compartments, said U- aped mem her havinga plurality of pairs of apertures therein, one aperture of each pairleading into one of said last-named compartments, and the other apertureof each pair leading into the Wind-chest.

11. In an organ, a sheet metal member having a substantially U-shape, ahorizontal partition extending from one side to the other of said memberand forming therewith a wind-chest, transverse vertically-extendingpartitions above said horizontal partition, said partitions forming aplurality of separate compartments, an upper board secured to the top ofsaid u shape member and having ports leading to each of said lattercompartments, pipes resting on said upper board, and means to controlcommunication be- 15 tween each of said compartments and the wind-chest.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
